US 5,957,056 A · Combined underground (over-ground) vehicle for public transport, for horizontal and steep metropolitan terrain

Abstract

An underground, on-ground or over-ground public transportation train-like vehicle that can move both on steep-slope terrain and horizontal or semi-horizontal terrain along a straight line or almost straight line route when seen from above, while remaining always in the same train configuration, enabling so the passengers to stay all the time in the same vehicle while moving between any two points at the same or different levels of a hilly city using the shortest in distance and time route, independently of weather conditions. A mobile cabin-to-cabin attachment enables the cabins of said train-like vehicle to vertically displace each with respect to the other and to horizontally rotate each with respect to the other, making thus possible for the passengers to remain in always-upright position and for the vehicle to move on a terrain with constantly changing slope, even when this change is abrupt, and not only along an ideally straight line. A 45.degree.-cabin-to-cable attachment device enables said train-like vehicle, cable-hauled along the sloped sections of the track, to deviate from the straight direction when seen from above, even along the steep sections of said track, between the stations as well as at the stations, without detachment from the cable.

Claims3

Dependent claims

A transportation system for transporting passengers, comprising:

a track system including at least a lower rigid track, an upper rigid track, and a cable track;
a vehicle adapted to be supported on said tracks, said vehicle including a plurality of interconnected cars connected one to another by a hinge and roller guide arrangement, and means mounted on said cars for supporting and guiding said vehicle on said lower track, upper track and cable track;
wherein said hinge and roller guide arrangement is attached between adjacent ones of said cars and includes hinges connected to at least one of the cars to allow relative horizontal rotations of the cars, and rollers arranged on vertical guides connected to said hinges and to an adjacent one of said cars so to allow relative vertical displacements of the cars;
and
wherein said means for supporting and guiding said vehicle includes a cable attachment device mounted on an upper part of the cars, said cable attachment device including a plurality of angled members, vertical and horizontal damping devices, and a cable gripping device interconnected one to another so as to attach the vehicle to the cable track at approximately 45 degrees relative to a vertical plane aligned with the longitudinal axis of the cable track.
